As a Scandinavian: I don't feel like we tried that since Braun. Apple has tried to mimic a Scandinavian sort of minimalism, but only in appearance. The iPhone UI is way to busy and is to hard to navigate for me to classify it as minimalism.
The problem with skeuomorphism in iOS' first design language was that resemblance to real-world objects was taken too far — at the expense of legibility. Users attributed affordances to virtual objects that they didn't have.
The problem with iOS 7's flatter interface was that the anti-skeumorphism went too far in the other direction, again at the expense of legibility. Users couldn't see what controls were supposed to do.
... And now the pendulum has swung back in the other direction, again too far, and missed the goal.
